Elastomeric tubular casings for drawstrings and a method of laundering accessories therewith

ABSTRACT

An elastomeric tubular casing encompasses an elongate, flaccid, textile article. The elastomeric tubular casing has a tube interior; a tube exterior; and tube first and second ends. The elastomeric tube in a first post-production orientation is rolled into a doughnut geometry, and adapted to unroll about the elongate, flaccid, textile article to resume a generally cylindrical tubular geometry, and thereby encase a portion of the textile article. According to a method of laundering an elongate, flaccid, textile article, the elongate, flaccid, textile article is encased with an elastomeric sleeve, the elastomeric sleeve having an interior diameter approximately equal to an exterior circumference of the elongate flaccid textile article and the elastomeric sleeve extending longitudinally co-extensively the elongate, flaccid textile article. The encased textile article is then laundered. The elastomeric sleeve is removed from the laundered textile article to yield a laundered, elongate, flaccid, textile article.

BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention pertains generally to textiles, and more particularly to accessories used with fluid treating apparatuses to facilitate the laundering of textiles, and to methods of laundering.

2. Description of the Related Art

Laundry equipment has always presented a challenge, both for the equipment designer and for the everyday user. In order to clean textiles such as clothing, towels, and the like, good contact with the wash water is vital. An excellent way to obtain good contact is to have a large differential in velocity between the garment and wash water. This translates into significant, even violent, movement between garment and wash water. Unfortunately, such significant movement is also extremely hard on more delicate clothing. Furthermore continued movement throughout a wash cycle can cause multiple rotations of garments, and the rotation may not affect the entire garment equally. Consequently, a designer must balance the cleaning ability against potential damage to the textile.

An everyday user faces similar challenge. All too often, drawstrings, laces and other similar components of laundry are twisted, stretched irreparably, or entangled destructively about other articles. While this is occurring, a drawstring will also be pulled through the channel in the clothing, and may be completely removed from the drawstring channel Historically, this has lead to the loss or destruction of valuable and sometimes irreplaceable items, and to substantially increased work loads re-threading drawstrings, neither which is desired.

SUMMARY OF THE INVENTION

In a first manifestation, the invention is, in combination, an elastomeric tubular casing and an elongate, flaccid, textile article. The elastomeric tubular casing has a tube interior; a tube exterior; a tube first end; and a tube second end distal to the tube first end. The elastomeric tube in a first post-production orientation is rolled into a doughnut geometry, and adapted to unroll therefrom about the elongate, flaccid, textile article to resume a generally cylindrical tubular geometry, and thereby encase a portion of the elongate, flaccid, textile article.

In a second manifestation, the invention is an elastomeric tubular casing. An elastomeric tube defines a tube interior, a tube exterior, a tube first end, and a tube second end distal to the tube first end. The tube interior further defines an adhesive surface, while the tube exterior defines a non-adhesive surface. A first gentle taper extends from a portion of the elastomeric tube exterior generally central between the tube first and second ends to the tube first end. A second gentle taper extends from a portion of the elastomeric tube exterior generally central between the tube first and second ends to the tube second end. The elastomeric tube in a first post-production orientation is rolled into a doughnut geometry, and adapted to unroll therefrom to resume a generally cylindrical tubular geometry.

In a third manifestation, the invention is a method of laundering an elongate, flaccid, textile article. According to the method, the elongate, flaccid, textile article is encased with an elastomeric sleeve, the elastomeric sleeve having an interior diameter approximately equal to an exterior circumference of the elongate flaccid textile article and the elastomeric sleeve extending longitudinally co-extensively the elongate, flaccid textile article to yield an encased, elongate, flaccid, textile article. The encased, elongate, flaccid, textile article is then laundered to yield a laundered, encased, elongate, flaccid, textile article. The elastomeric sleeve is removed from the laundered, encased, elongate, flaccid, textile article to yield a laundered, elongate, flaccid, textile article.

OBJECTS OF THE INVENTION

Exemplary embodiments of the present invention solve inadequacies of the prior art by providing an apparatus to secure drawstrings and the like during laundering and, in some embodiments for general aesthetic and functional purpose as well.

The present invention and the preferred and alternative embodiments have been developed with a number of objectives in mind. While not all of these objectives are found in every embodiment, these objectives nevertheless provide a sense of the general intent and the many possible benefits that are available from embodiments of the present invention.

A first object of the invention is to secure drawstrings and prevent them from being retracted through a drawstring tunnel. A second object of the invention is to stiffen drawstrings and similar long and flaccid textile accessories sufficiently to prevent them from entangling with other textiles during laundering. An additional object of the invention is to provide an internal surface that exhibits high adhesion and grab relative to an external surface that exhibits low adhesion and grab. Another object of the present invention is to incorporate various degrees of card, picture or sign exhibiting. A further object of the invention is to make smaller textile accessories such as drawstrings easier to grasp and hold. Yet another object of the present invention is to provide an ornate appearance to otherwise utilitarian articles. An additional object of the invention is to limit or control fraying of a lace or drawstring.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Manifested in the preferred embodiment, the present invention provides an elastomeric tubular casing that may be applied to drawstrings, and a method of laundering accessories using the elastomeric tubular casing.

In a preferred embodiment of the invention illustrated in FIGS. 1-4, elastomeric tubular casing 10 for drawstrings and laundering accessories is comprised of an elastomeric tube 11 most preferably having gentle tapers 12, 13 extending from intermediate along tube 11 to distal ends 14, 15, respectively, of tube 11. Optionally the ends 14, 15 are provided with slight bevels.

FIG. 5 illustrates preferred embodiment elastomeric tubular casing 10 in further combination with, co-extensive with, and generally co-axial about a drawstring 1. The particular drawstring 1 will be understood herein to include not only drawstrings but other types of strings, lacing, and other flaccid and longitudinally extensive objects as well, and so may comprise a shoe string, a drawstring, or any other sort of lacing, string or other flaccid article.

Preferred embodiment elastomeric tubular casing 10 performs a number of useful and beneficial functions when used in combination with a drawstring 1 or the like. The enlarged diameter and improved feel provided by preferred embodiment elastomeric tubular casing 10 makes articles easier to grasp and hold. This can be particularly beneficial to young children, elderly persons, and any other persons who would like to more easily grasp and hold a drawstring or the like. In addition, a preferred embodiment elastomeric tubular casing 10 may incorporate various degrees of card, picture or sign exhibiting, such as custom logos or the like displayed along the exterior of elastomeric tube 11. Furthermore, a preferred embodiment elastomeric tubular casing 10 may be used to provide an ornate appearance to otherwise utilitarian articles. In this case, the exterior diameter of elastomeric tube 11 might, for exemplary and non-limiting purposes, be of varying diameter rather than the constant outside diameter illustrated in the present Figures. Similarly, diverse colors, fills such as glitter or the like, and patterns may be used to provide further ornamentation. While only one preferred embodiment elastomeric tubular casing 10 is illustrated as being affixed with drawstring 1 in FIG. 5, it will be understood herein that as many tubular casings 10 may be applied to a drawstring 1 or the like as desired by a person. Particularly where there are a variety of ornamentations available in otherwise functionally similar tubular casings 10, a person can generate diverse and unique appearance along the length of drawstring 1.

As an analog thereto, a combination of silicone with phosphorescent and radiant compounds offers several benefits. A first benefit comes in increased night or low-light visibility of a person wearing a preferred embodiment elastomeric tubular casing 10 so compounded. This glow can also be useful in locating missing apparel.

Another benefit of preferred embodiment elastomeric tubular casing 10 is that it inherently limits or controls fraying 2 of a lace or drawstring, generally inhibiting fraying 2 from propagating beyond the end 14 which defines an inlet or entry of drawstring 1 into preferred embodiment elastomeric tubular casing 10.

Yet another benefit, the significance which cannot be overstated, is when a preferred embodiment elastomeric tubular casing 10 is applied to the laundering of articles of clothing. As already noted herein above, drawstrings, laces and other similar components of laundry are all too commonly twisted, stretched irreparably, or entangled destructively about other articles. While this is occurring, a drawstring will also be pulled through the channel in the clothing, and may be completely removed from the drawstring channel Historically, this has lead to the loss or destruction of valuable and sometimes irreplaceable items, and to substantially increased work loads re-threading drawstrings, neither which is desired.

By affixing preferred embodiment elastomeric tubular casing 10 about both ends of a drawstring 1, drawstring 1 cannot be retracted through the drawstring hole, owing to the enlarged diameter of the elastomeric tube 11. This prevents a particularly long exposed drawstring 1 from floating about and entangling other textiles during laundering. Furthermore, a significant portion of drawstring 1 that protrudes from the drawstring hole is covered by preferred embodiment elastomeric tubular casing 10, and so is much more difficult to twist and entangle. Consequently, not only does preferred embodiment elastomeric tubular casing 10 designed in accord with the teachings of the present invention provide an ornate appearance, there will also often be significant time savings and protection of drawstrings and more delicate articles in the laundry and otherwise.

Gentle tapers 12, 13 and bevels at ends 14, 15 each form a more gradual transition between drawstring 1 and the preferred embodiment elastomeric tubular casing 10. This is felt to be both aesthetically pleasing, and also functionally more proficient, since preferred embodiment elastomeric tubular casing 10 for drawstrings and laundering accessories will be less likely to be snagged, rolled or otherwise entangled with other objects.

In accord with the teachings of the present invention, a suitable material for preferred embodiment elastomeric tubular casing 10 will be one which is elastomeric, permitting limited flexure. Furthermore, elastomeric materials impact other objects with a softened, deadened and ordinarily non-marring blow. This means that, in laundry applications, a preferred embodiment elastomeric tubular casing 10 will not rattle or clank about in the clothes dryer. Elastomers are a broad class of materials, and may for exemplary and non-limiting purposes include both natural and synthetic rubbers, as well as certain co-polymers, highly plasticized polymers, and certain highly cross-linked polymers. They are typically characterized by glass transition temperatures that are well below room temperature, meaning that at room temperature they exist in a rubber-like state.

Materials that can withstand the heat of a dryer or hot or steamed water, as typically found in laundering applications, are further preferred. However, since the glass transition temperature will typically be well below room temperature to obtain the elastomeric characteristics, this further means the material must also have a very wide temperature range between the polymer glass transition temperature and softening point. For laundering applications then, some highly plasticized polymers will exceed a reasonable softening point in the washer or drier and will be damaged, further limiting the selection of materials.

Substantial elasticity is also desirable. A preferred embodiment elastomeric tubular casing 10 for drawstrings and laundering accessories may preferably be rolled at the time of production for shipment and delivery, such as illustrated in FIGS. 6-9. As shown therein, taper 12 has been substantially rolled, by beginning the roll at end 14 and rolling towards end 15. As taper 12 rolls upon itself, an increasing number of coaxial layers are defined, as shown in FIG. 8 where 12 a designates the outermost rolled portion of taper 12, and 12 b represents the more inner roll of taper 12. This is also apparent from FIG. 9, and, as can be understood, when taper 12 is completely rolled the balance of preferred embodiment elastomeric tubular casing 10 may also be rolled, eventually forming what might appear to be a simple “o” having left and right side elevational views similar to FIG. 6, but which actually comprises many co-axial layers such as layers 12 a and 12 b. As can be appreciated, this rolling requires a great deal of elasticity.

An important benefit of this rolling is the ease of application of a preferred embodiment to an article of clothing. The preferred embodiment elastomeric tubular casing 10 may simply be slid onto the article to a desired starting position, and unrolled from there onto the article. Consequently, the fully rolled configuration is preferred for delivery to a customer for use.

Using the rolled configuration of FIGS. 6-9 enables another preferred feature, which is to provide an interior surface of the preferred embodiment elastomeric tubular casing 10 for drawstrings and laundering accessories that has a very high adhesion characteristic. This helps to secure the preferred embodiment elastomeric tubular casing 10 to an article such as a drawstring 1 without annoying sliding or slipping that may otherwise require frequent and sometimes difficult readjustments. The adhesion characteristic may be obtained in any suitable way, but will preferably be enduring. For exemplary purposes only, and not solely limiting thereto, the interior surface may be chemically, mechanically or otherwise treated, or may alternatively be coated, laminated, impregnated with, or otherwise combined with another material that generates the desirable adhesion characteristic.

One particularly suitable material for preferred embodiment elastomeric tubular casing 10 that is commonly available is a silicone rubber. Most silicone compositions offer the advantages of being highly chemically inert, meaning they can withstand the use of powerful cleaning compounds and solvents that may be encountered in the laundry. Furthermore, they have an exceptionally wide elastomeric temperature range, and will withstand the extremes of terrestrial cold and the heat of a clothes drier. Silicone compositions may also be customized to control the adhesion characteristic of a surface, allowing the inner surface to have high or elevated adhesion characteristic above a standard adhesion, while the outer surface may be provided with a lowered or relatively more non-stick surface. In other words, for the purposes of the present disclosure high adhesion will be understood to include either of adhesion greater than a standard adhesion for a typical composition, or adhesion relatively higher than a second adhesion, with the second adhesion then being deemed a low or non-stick adhesion.

A non-stick exterior helps to prevent surrounding materials or objects from clinging to or becoming entangled with preferred embodiment elastomeric tubular casing 10. This can be particularly critical in laundry applications, where it is desirable not to tangle or damage adjacent articles of clothing. Most preferably, a preferred embodiment elastomeric tubular casing 10 will have a powder-like feeling on the exterior, and a sticky feeling on the interior. This non-stick characteristic of the exterior surface may be achieved in any suitable manner. For exemplary purposes only, and not solely limiting thereto, the exterior surface may be chemically, mechanically or otherwise treated, or may alternatively be coated, laminated, impregnated with, or otherwise combined with another material that generates the desirable adhesion characteristic. In the case of a silicone composition, a mold exterior may be sandblasted or otherwise treated to roughen the surface. The resulting preferred embodiment elastomeric tubular casing 10 will exhibit less grab on the exterior if so treated.

Various embodiments of apparatus designed in accord with the present invention have been illustrated in the various figures. While FIGS. 1-9 illustrate a preferred embodiment, additional alternative embodiments are illustrated in FIGS. 10-13, FIG. 14, and FIG. 15, respectively. The embodiments are distinguished by the hundreds digit, and various components within each embodiment designated by the ones and tens digits. However, many of the components are alike or similar between embodiments, so numbering of the ones and tens digits have been maintained wherever possible, such that identical, like or similar functions may more readily be identified between the embodiments. If not otherwise expressed, those skilled in the art will readily recognize the similarities and understand that in many cases like numbered ones and tens digit components may be substituted from one embodiment to another in accord with the present teachings, except where such substitution would otherwise destroy operation of the embodiment. Consequently, those skilled in the art will readily determine the function and operation of many of the components illustrated herein without unnecessary additional description.

FIGS. 10-13 illustrate a first alternative embodiment elastomeric tubular casing 110 for drawstrings and laundering accessories from various views corresponding to those of FIGS. 1-4. This first alternative embodiment is very similar to the preferred embodiment elastomeric tubular casing 10 of FIG. 1, but has been designed to be of significantly smaller inside and outside diameter. As may be apparent from these FIGS. 10-13, tubular casing 110 may be sized to fit smaller circumference articles and larger circumference articles, and may have different degrees of end taper. The elastomeric tube 111, gentle tapers 112, 113, and distal ends 114, 115 are likewise of smaller outside and inside diameter, but are also otherwise similar to the corresponding components found in preferred embodiment elastomeric tubular casing 10.

FIG. 14 illustrates a second alternative embodiment elastomeric casing 210 for laundering accessories. Two very similar or symmetrical clamshell halves 220, 230 are coupled together at hinge 240, permitting the halves 220, 230 to pivot from the generally in-line geometry illustrated in FIG. 14 to a side-by-side relationship that captures a drawstring 1 therein. Clamshell half 220 has a pair of side rails 221, 222 and a plurality of rungs 223 extending transversely between side rails 221, 222. Clamshell half 230 has a similar pair of side rails 231, 232 and a plurality of rungs 233 extending transversely between side rails 231, 232. At ends of clamshell halves 220, 230 distal to hinge 240 are couplers 224, 234, respectively that are designed to couple together. For exemplary and non-limiting purposes, these couplers 224, 234 might comprise snap fasteners or any other suitable couplers.

Most preferably, couplers 224, 234 will be readily manipulable, and capable of repeated coupling and decoupling. Similarly, plastic hinges 241, 242 are preferably capable of repeated flexure and straightening. This combination allows a person to insert a drawstring 1 or the equivalent through a hinge area opening 243, then collapse clamshell halves 220, 230 together in the manner of a clamshell so as to close about drawstring 1 and bring rungs 223 immediately adjacent to rungs 233, and finally snap couplers 224, 234 together to affix second alternative embodiment elastomeric casing 210 prior to laundering. When laundering is complete, a person can then separate couplers 224, 234, and remove second alternative embodiment elastomeric casing 210 from drawstring 1, allowing second alternative embodiment elastomeric casing 210 to be reused as any times as hinge 240 and couplers 224, 234 continue to function properly.

If plastic hinges 241, 242 are slightly offset from centered between the most adjacent rungs 223, 233, then rungs 223 will nest with rungs 233 when clamshell halves 220, 230 are folded together in the manner of a clamshell. This means that a drawstring 1 will serpentine between adjacent rungs. Alternatively, if plastic hinges 241, 242 are centered between the most adjacent rungs 223, 233, then rungs 223 will instead press against rungs 233 when clamshell halves 220, 230 are folded together in the manner of a clamshell. In this case, drawstring 1 may pass relatively straight through, but will be pinched between opposed rungs 223, 233.

FIG. 15 illustrates a third alternative embodiment elastomeric apparatus 310 for laundering accessories. As illustrated therein, a slab 340 has at least one and preferably a plurality of binding holes 350 formed therein. The manner of formation is not critical to the present invention, and may include punching, molding, cutting, or any other suitable technique.

Each binding hole 350 has a pair of cantilevers 352, 354 that project from opposite edges towards each other into binding hole 350. As a result, binding hole 350 reassembles the shape of an “H”, having two open strips 357, 358 and a relatively smaller opening 356 between the open strips 357, 358.

Most preferably, third alternative embodiment elastomeric apparatus 310 is fabricated from a medium durometer material. In use, a person will weave a drawstring such as drawstring 1 from above the visible major surface of slab 340 down through open strip 357, under cantilevers 352, 354, and then back up through open strip 358 to return to above the visible major surface of slab 340. The use of cantilevers 352, 354 in combination with a medium durometer material will preferably allow a person to flex these cantilevers 352, 354 out of the way and simply press a small loop or length of a drawstring down into opening 350. Once the small loop of drawstring passes the cantilevers 352, 354, these cantilevers 352, 354 can then pop back up into the opening, thereby gently securing the drawstring therein. Alternatively, with a higher durometer and thereby stiffer composition, a flat drawstring 1 may be partially rotated to pass through relatively smaller opening 356, and then allowed to straighten and thereby engage with cantilevers 352, 354.

While the foregoing details what are felt to be the preferred and alternative embodiments of the invention, no material limitations to the scope of the claimed invention are intended. Further, features and design alternatives that would be obvious to one of ordinary skill in the art are considered to be incorporated herein.
